Further state of the art are EP 2 420 362 B1 and US Pat. No. 6,640,681 B1. In these so-called "slicers" rod-shaped or differently shaped food bars, such as sausage, cheese, ham, raw ham or the like with a very high cutting performance, for example, up to 1,000 cuts per minute or more, in

Bei diesem Gegenstand der vorliegenden Erfindung erfolgt Vorschub des In this object of the present invention, feed of the
Lebensmittelriegels während des Abtrennens einer Trimmscheibe mit zwei unterschiedlichen Geschwindigkeiten. Vorzugsweise wird der Lebensmittelriegel, insbesondere während das Schneidmesser nicht mit ihm in Eingriff ist mit einer Geschwindigkeit, die über der Food bars during the separation of a trim disc with two different speeds. Preferably, the food bar, in particular during the Cutting knife is not engaged with it at a speed exceeding that
Nennvorschubgeschwindigkeit beim Abschneiden von Nennlebensmittelscheiben liegt, um einen vergleichsweise großen Weg, beispielsweise 2 - 34 mm, vorzugsweise 5 - 30 mm bewegt. Danach, insbesondere wenn das Schneidmesser im Kontakt mit dem Nominal feed rate when cutting nominal food discs is moved by a comparatively long way, for example 2 - 34 mm, preferably 5 - 30 mm. Thereafter, especially if the cutting blade in contact with the
Lebensmittelriegel ist, wird eine andere, insbesondere reduzierte Geschwindigkeit, insbesondere auf die Nennvorschubgeschwindigkeit reduzierte Vorschubgeschwindigkeit gewählt. Food bar is, another, especially reduced speed, in particular to the nominal feed speed reduced feed rate is selected.
Zwischen den beiden oben erwähnten Geschwindigkeiten kann die Vorschubgeschwindigkeit kurzzeitig auf null oder nahe null m/s reduziert werden. Between the two speeds mentioned above, the feed rate can be briefly reduced to zero or near zero m / s.
Diese Verfahrensweise kann zum Abschneiden eines oder mehrerer Trimmschnitte eingesetzt werden. Insbesondere kann der letzte Trimmschnitt gemäß diesem Verfahren abgeschnitten werden. Der/die Trimmschnittscheiben sind dann jeweils leicht keilförmig. This procedure can be used to cut off one or more trimming cuts.

Trimmlebensmittelscheibe zumindest im Wesentlichen dieselbe Drehzahl hat wie während des Aufschneidens mindestens einer Portion aus Nennlebensmittelscheiben. Trimmlebensmittelscheibe has at least substantially the same speed as during the slicing of at least a portion of nominal food slices.
Die zu diesem Gegenstand der vorliegenden Erfindung gemachten Ausführungen gelten für die anderen Gegenstände gleichermaßen und umgekehrt. The statements made on this subject of the present invention apply equally to the other objects and vice versa.
Bei diesem Gegenstand der vorliegenden Erfindung dreht sich das Schneidmesser zumindest beim Abtrennen der letzten Trimmlebensmittelscheibe zumindest im Wesentlichen mit der im Nennbetrieb gewünschte Drehzahl. Mit dem Aufschnitt der In this object of the present invention, the cutting blade rotates, at least when separating the last trim food disc at least substantially with the desired speed at rated operation. With the cold cuts of
Nennlebensmittelscheiben im Nennbetrieb kann dann unmittelbar weitergemacht werden, ohne dass das Schneidmesser nennenswert beschleunigt werden muss. Nominal food slices in rated operation can then be continued immediately, without the cutting blade has to be significantly accelerated.
Vorzugsweise fallen die Trimmlebensmittelscheiben auf den Ablagetisch und werden von dort entsorgt.„Entsorgt" bzw.„sekundär verwertet" im Sinne der Erfindung bedeutet, dass die Trimmlebensmittelscheiben nicht in dieselbe Richtung wir die Portionen aus The trimmed food slices preferably fall on the storage table and are disposed of there. "Disposed" or "secondarily utilized" in the sense of the invention means that the trim food slices do not leave the portions in the same direction
Nennlebensmittelscheiben transportiert werden. Bei mehr als einer Trimmlebensmittelscheibe pro Lebensmittelriegel werden diese Scheiben vorzugsweise auf dem Ablagetisch gesammelt und dann gemeinsam abtransportiert. Nominal food discs are transported. With more than one Trimmlebensmittelscheibe per food bar these slices are preferably collected on the table and then transported together.
Gemäß einer bevorzugten Ausführungsform wird der Lebensmittelriegel vor dem According to a preferred embodiment, the food bar before the
Aufschneiden gescannt und die Anzahl und/oder die Dicke der Trimmlebensmittelscheibe(n) vorab festgelegt. Erst nachdem dieser Abschnitt des Lebensmittelriegels abgetrennt worden ist, kann mit dem Aufschneiden von Nennlebensmittelscheiben begonnen werden. Scanned and the number and / or the thickness of the trim food disc (s) pre-determined. Only after this section of the food bar has been separated can the slicing of nominal food slices be started.
Vorzugsweise wird, insbesondere beim Scannen, beispielsweise beim Röntgenscannen, die lokale Dichte des Lebensmittelriegels ermittelt wird und anhand der Dichte die Einteilung in Trimm- oder Nennscheibe erfolgt. Dazu wird besonders bevorzugt ein Referenzwert festgelegt, anhand dessen entschieden wird, in welche der beiden Klassen eine Scheibe fällt. Alternativ oder zusätzlich kann zum Klassieren auch mindestens eine geometrische Abmessung herangezogen werden, die die Grenz darstellt, ab derer eine Scheibe eine Trimm- oder eine Nennscheibe ist. Preferably, in particular during scanning, for example in the case of X-ray scanning, the local density of the food bar is determined and the division into trim or nominal disk takes place on the basis of the density. For this purpose, a reference value is particularly preferably determined, by means of which it is decided in which of the two classes a disc falls. Alternatively or additionally, at least one geometric dimension can be used for classifying, which represents the limit beyond which a disc is a trim or a nominal disc.
Vorzugsweise wird das Schneidmesser vorm und/oder beim Wiederbeladen abgebremst. Mit dieser abgebremsten Drehzahl können die Trimmlebensmittelscheiben von dem Preferably, the cutting blade is braked before and / or during reloading. With this braked speed, the trim food slices of the
Lebensmittelriegel abgetrennt werden. Dabei oder danach wird das Schneidmesser dann wieder beschleunigt. Food bars are separated. During or after the cutting blade is then accelerated again.
Gemäß einer bevorzugten Ausführungsform der vorliegenden Erfindung werden mehrere Lebensmittelriegel gleichzeitig aufgeschnitten. Dabei kann jeder Lebensmittelriegel eine eigene Spur haben. Die Lebensmittelriegel können gemeinsam oder individuell angetrieben werden. According to a preferred embodiment of the present invention, several food bars are cut simultaneously. Each food bar can have its own track. The food bars can be driven together or individually.
Im Folgenden wird die Erfindungen anhand der Figuren 1 - 5 und einem Ausführungsbespiel erläutert. Diese Erläuterungen sind lediglich beispielhaft und schränken den allgemeinen Erfindungsgedanken nicht ein. In the following, the inventions will be explained with reference to FIGS. 1-5 and an exemplary example. These explanations are merely exemplary and do not limit the general inventive concept.
Figur 1 zeigt eine Aufschneidevorrichtung. FIG. 1 shows a slicing device.
Figuren 2 und 3 zeigen die Durchführung von Trimmschritten und das Abtrennen von  Figures 2 and 3 show the implementation of trim steps and the separation of
Nennlebensmittelscheiben gemäß dem Stand der Technik.  Rated food slices according to the prior art.
Figuren 4 und 5 zeigen die erfindungsgemäße Durchführung von Trimmschritten und das erfindungsgemäße Abtrennen von Nennlebensmittelscheiben. Figur 1 zeigt eine Aufschneidevorrichtung 5. Die Aufschneidevorrichtung 5 weist ein FIGS. 4 and 5 show the implementation of trim steps according to the invention and the separation of nominal food slices according to the invention. 1 shows a slicing device 5. The slicing device 5 has a
Schneidmesser 1 1 auf, das ein Lebensmittelprodukt 2 in Nennlebensmittelscheiben 12 schneidet. Dazu wird jedes Lebensmittelprodukt 2 mit einem Fördermittel 4, hier zwei Förderbändern 4, kontinuierlich in Richtung der Schneidebene 6 des Messers 1 1 Cutting knife 1 1, which cuts a food product 2 in nominal food slices 12. For this purpose, each food product 2 with a conveyor 4, here two conveyor belts 4, continuously in the direction of the cutting plane 6 of the knife 1 first
transportiert. Das untere Förderband 4 ist gleichzeitig eine Produktauflage. Das transported. The lower conveyor belt 4 is at the same time a product support. The
Schneidmesser 1 1 ist an einer sich drehenden Messeraufnahme 3 befestigt und wirkt vorzugsweise mit einer Schneidkante schneidend zusammen, die beispielsweise am vorderen Ende einer Produktauflage 4 vorgesehen ist und die vorzugsweise gemeinsam die Schneidebene definieren. Zwischen dem Messer 1 1 und der Schneidkante ist ein Cutting knife 1 1 is attached to a rotating blade holder 3 and preferably cooperates with a cutting edge cutting, which is provided for example at the front end of a product support 4 and preferably together define the cutting plane. Between the knife 1 1 and the cutting edge is a
sogenannter Schneidspalt vorhanden, der möglichst klein sein sollte, jedoch so groß sein muss, dass das Messer die Schneidkante nicht berührt. Dieser Spalt muss regelmäßig eingestellt werden. Dies kann durch eine Bewegung des Messers und/oder der so-called cutting gap present, which should be as small as possible, but must be so large that the knife does not touch the cutting edge. This gap must be adjusted regularly. This can be done by a movement of the knife and / or the
Schneidkante erfolgen. Außerdem muss die Schneidkante parallel zu dem Messer ausgerichtet sein. Nach dem Abschneiden fallen die Nennlebensmittelscheiben in der Regel auf einen Ablagetisch 1 , der mit Transportmitteln, beispielsweise einem Transportband oder Transportriemen, versehen ist, auf dem sie zu jeweils einer Portion 14, hier einem Stapel, konfiguriert werden. Die fertiggestellten Portionen 14 werden sodann aus dem Cutting edge done. In addition, the cutting edge must be aligned parallel to the knife. After cutting, the nominal food slices usually fall on a storage table 1, which is provided with means of transport, for example a conveyor belt or conveyor belt, on which they are each configured to a portion 14, here a stack. The finished portions 14 are then from the
Schneidmesserbereich abtransportiert und danach verpackt. Die Scheibenstärke ergibt sich aus der Vorschubstrecke des Lebensmittelproduktes zwischen zwei Schnitten. Bei konstanter Messerdrehgeschwindigkeit erfolgt die Regelung der Scheibenstärke über die gewünschte Vorschubgeschwindigkeit des Lebensmittelproduktes. Auch während des Schnitts wird der Lebensmittelriegel kontinuierlich weitertransportiert. Die Cutting knife area removed and then packed. The slice thickness results from the feed distance of the food product between two cuts. At constant blade rotation speed, the regulation of the slice thickness is carried out via the desired feed rate of the food product. Also during the cutting, the food bar is continuously transported. The
Aufschneidevorrichtung kann pro Vorschubtrasse 8 einen Greifer aufweisen, der das rückwärtige Ende 13 des Lebensmittelproduktes 2 vor oder während des Aufschneidens ergreift und dieses während des Aufschneidens, insbesondere gegen Ende des Slicing device may have per feed path 8 a gripper which engages the rear end 13 of the food product 2 before or during the slicing and this during slicing, in particular towards the end of
Aufschneidens, stabilisiert und das Endstück, das nicht aufgeschnitten werden kann, entsorgt. Jeder Greifer ist vorzugsweise an einem Greiferwagen (nicht dargestellt) vorgesehen, der die Greifer, insbesondere parallel zur Vorschubrichtung des Slicing, stabilized and disposed of the tail that can not be cut. Each gripper is preferably provided on a gripper carriage (not shown) which holds the grippers, in particular parallel to the feed direction of the gripper
Lebensmittelprodukts, vor- und zurückbewegt. Food product, moved back and forth.
Vorzugsweise ist die Aufschneidevorrichtung mehrspurig vorgesehen, d.h. dass mehrere Lebensmittelprodukte 2 von einem Messer, insbesondere zumindest zeitweise gleichzeitig oder zumindest zeitweise sequentiell, aufgeschnitten werden. Dafür weist die Vorrichtung für jedes Lebensmittelprodukt eine eigene Spur 8 auf, entlang derer es in Richtung des Messers 1 1 transportiert wird. Die abgeschnittenen Lebensmittelscheiben werden jeweils zu Portionen konfiguriert. Stromabwärts von dem Ablagetisch 1 ist in der Regel ein Verteiler vorgesehen, der die Portion(en) von dem Ablagetisch übernimmt und beispielsweise an einen zweiten Verteiler oder einen Einleger übergibt, der die Portionen in Verpackungsmulden einlegt. Preferably, the slicing device is provided in multiple tracks, ie that several food products 2 are cut open by a knife, in particular at least temporarily at the same time or at least temporarily sequentially. For this purpose, the device has for each food product its own track 8, along which it is transported in the direction of the knife 11. The cut food slices are each configured into portions. Downstream of the storage table 1, a distributor is generally provided, which takes over the portion (s) from the delivery table and, for example, transfers them to a second distributor or depositor, who inserts the portions in packaging troughs.
Figur 2 zeigt das Abtrennen von Trimmlebensmittelscheiben von dem Lebensmittelriegel 2 gemäß dem Stand der Technik. Um das Trimmstück 2' von dem Lebensmittelriegel abzutrennen, müssen in dem vorliegenden Fall beispielhaft drei Trimmschnitte 10 durchgeführt werden. Dabei erfolgt der Transport des Lebensmittelriegels intermittierend, d.h. sobald das vordere Ende des Lebensmittelriegels die gewünschte Position erreicht hat, wird der Lebensmittelriegel angehalten und die Trimmlebensmittelscheibe abgetrennt und so dann der Lebensmittelriegel weitertransportiert bis die nächste Trimmschnittposition erreicht ist usw. Figure 2 shows the separation of trim food slices from the food bar 2 according to the prior art. In order to separate the trim piece 2 'from the food bar, in the present case three trimming cuts 10 have to be made by way of example. The transport of the food bar takes place intermittently, i. as soon as the front end of the food bar has reached the desired position, the food bar is stopped and the trim food slice is separated and then transported to the food bar until the next trim cut position is reached, etc.
Sobald die gewünschte Größe des Trimmschnitts 2' abgetrennt worden ist, erfolgt das Aufschneiden der ersten Portion von Lebensmittelscheiben, die sodann portioniert und verpackt werden sollen. Dafür wird der Lebensmittelriegel auf die gewünschte Once the desired size of Trimmschnitts 2 'has been separated, the cutting of the first portion of food slices, which are then portioned and packaged. For the food bar is on the desired
Vorschubgeschwindigkeit beschleunigt, die auch während des Schnittes beibehalten wird. Dadurch ist die erste Lebensmittelscheibe, wie in Figur 3 dargestellt, keilförmig, was unerwünscht ist. Speeds up feed rate, which is maintained during the cut. As a result, the first food disc, as shown in Figure 3, wedge-shaped, which is undesirable.
Um dies zu vermeiden, wird, erfindungsgemäß vorgesehen, dass der Lebensmittelriegel auch beim Abtrennen der Trimmlebensmittelscheiben 9 mit der To avoid this, is provided according to the invention, that the food bar 9 also with the separation of the trim food discs with the
Nennvorschubgeschwindigkeit für das Abtrennen von Nennlebensmittelscheiben 12 in Richtung des Schneidmessers transportiert wird. Dadurch ist die erste verwertbare Nominal feed rate for the separation of nominal food discs 12 is transported in the direction of the cutting blade. This is the first usable
Nennlebensmittelscheibe 12 nicht mehr keilförmig, sondern weist eine in wesentlichen konstante Dicke auf. Nominal food disc 12 no longer wedge-shaped, but has a substantially constant thickness.
Gemäß dem Stand der Technik wurde nach dem Abtrennen der letzten According to the prior art, after the separation of the last
Trimmlebensmittelscheibe der Vorschub des Lebensmittelriegels unterbrochen und Dieser ausgesetzt, bis das Messer auf seine Nenndrehzahl beschleunigt worden war. Erst dann wurde der Vorschub des Lebensmittelriegels wieder in Gang gesetzt. Trim food slice the feed of the food bar interrupted and suspended until the knife had been accelerated to its rated speed. Only then was the feed of the food bar started again.
Um diesen Zeitverlust zu vermeiden, wird, gemäß einer Ausführungsform der vorliegenden Erfindung, die Drehzahl des Schneidmessers während des Aufschneidens einer oder mehrerer Nennlebensmittelscheiben oder mindestens einer Portion bestehend aus In order to avoid this loss of time, according to one embodiment of the present invention, the speed of rotation of the cutting blade during the slicing of one or more nominal food slices or at least one portion consisting of
Nennlebensmittelscheiben beschleunigt, bis die gewünschte Nenndrehzahl erreicht ist. Alternativ oder zusätzlich kann diese Beschleunigung auch während des Abtrennens von Trimmlebensmittelscheiben erfolgen, so dass das Schneidmesser die gewünschte Nominal food slices accelerated until the desired rated speed is reached. Alternatively or additionally, this acceleration can also take place during the separation of trim food slices so that the cutting knife achieves the desired
Nenndrehzahl aufweist, sobald die erste Nennlebensmittelscheibe abgeschnitten werden soll. Rated speed, as soon as the first nominal food slice is to be cut off.
Figur 4 zeigt das erfindungsgemäße Verfahren. Das Abtrennen der Trimmschnitte erfolgt beispielsweise intermittierend. Bei der Durchführung des Trimmschnitts wird der FIG. 4 shows the method according to the invention. The separation of the trimming cuts, for example, intermittently. When performing the trim section of the
Lebensmittelriegel nicht bewegt. Erst bei dem oder den letzten Trimmschnitten erfolgt die Beschleunigung des Lebensmittelriegels auf Nennvorschubgeschwindigkeit. Dadurch wird die letzte Trimmscheibe keilförmig, die erste zu verwendende Lebensmittelscheibe weist jedoch eine konstante Dicke auf, was in Figur 5 zu sehen ist. Das kann sich auch während des Abtrennens einer Trimmscheibe mit der Nenndrehzahl drehen. Food bar does not move. Only at the last trim cuts or the acceleration of the food bar is at nominal feed speed. As a result, the last trimming disc becomes wedge-shaped, but the first food disc to be used has a constant thickness, which can be seen in FIG. This can also rotate while disconnecting a trim disk at rated speed.
Gemäß einem Ausführungsbeispiel erfolgt der Trimmschnitt, insbesondere mit einer Scheibendicke >5mm, mit einer vergleichsweise niedrigeren Schnittgeschwindigkeit, beispielsweise 50-300UPM. Bei dieser Ausführungsform kann der Vorschub des According to one embodiment, the trimming cut, in particular with a slice thickness> 5 mm, takes place with a comparatively lower cutting speed, for example 50-300 rpm. In this embodiment, the feed of the
Lebensmittelriegels zwischen zwei Schnitten intermittierend ausgeführt werden, d.h. beim eigentlichen Schnitt wird der Lebensmittelriegel nicht vorgeschoben. Die letzte Food bars are intermittently executed between two cuts, i. during the actual cut, the food bar is not advanced. The last
Trimmschnittscheibe kann erst intermittierend zur Schneidkante bewegt werden. Wenn das Messer in das Produkt eintritt, wird auf die Vorschubgeschwindigkeit der Nennscheibendicke umgeschaltet. Ab diesem Zeitpunkt beschleunigt das Messer während dem Schneiden auf die Nennschnittzahl, zum Beispiel 600- 1500UPM. Alle relevanten Antriebe (Vorschub, Traktionssysteme, Portionier Bänder, ...) können, vorzugsweise synchron, mit der Trimmschnittscheibe can only be moved intermittently to the cutting edge. When the knife enters the product, it switches to the feed speed of the nominal wheel thickness. From this point on, the knife accelerates to the nominal cutting number during cutting, for example 600-1500UPM. All relevant drives (feed, traction systems, portioning belts, ...) can, preferably synchronously, with the
Messerdrehzahl mitbeschleunigt werden. Knife speed mitbeschleunigt.
Es ist aber auch möglich, dass die Vorschubgeschwindigkeit für die Nennscheibendicke bei allen Trimmschnitten ansteht und der intermittierende Vorschub dazu geschaltet wird.  But it is also possible that the feed rate for the nominal wheel thickness is present at all trim cuts and the intermittent feed is switched to it.
Dadurch sind alle Trimmscheiben leicht keilförmig. As a result, all trims are slightly wedge-shaped.
